'1111S pfocess is substontiany charaoterized by the faot that Sevefa1 gfound textufes and a single oovefing afe sinlultoneous1y vvoven, the fnter1acing orbfnding being effeoted in such a. fflonner that, fvhen the oovering threadS afe cut, aJ pof fion of thiS oover1ng is integfa1 with eacff gfound textufe, thus pfoduofng Sevefa1 pieces of fancy velvet. or inStance, in the case of two ground textures, the portfons oovered vvith pile on one of soid textufes afe con1plenlentofy to tf1OSe vvitholft pfle of the othef texture.

,I'11einventionfS applioable aS vve11 to warp pile fobrics os to Woft pne fabrics, but its applicotion s palficulofly advontageous for Weff pile fabrIoS.

descrfption wi1 fifst be given in order to show how the inventfon can be carfied into pfoctice in the case of vveft pile fabffos.

T'he distributfon of the pile is effected on sev era1 ground textoIeS SiTnultaneously woven ac oofding to the distribution, on one or the other of these textufeS, of the binding points of the pie 1oopS.

The outting being subsequent1y effected by the usoo1 Inethods, the sepafotion of the gfound textureS oefeTmines as fnony fabrics variously covefed vvfth pile, and of oovefing oofnplen1entofy to each other.

f1fter o11tting the oovefing thfeads, tvvo pieces of openvvofk pfle P 1 (,ig. 3) afe obtained, vhioh caffy pile of places coInp1ementary to each othef, that is to say the porfions oovered Xvith pile of one pfeoe co respond to the apertures of the othef.

AS poftioulof deSfgn Which may be obtained, the 1oops f of P can fofIn o cheok pattern, and the 1oops o of P another oheok pattern (Fig. the apeftufeS of one pieoe coffesponding to the Sond. poftions of the othef.

The neW pfoceSs pfeSents, in the ooSe of vveft pile fa.bric, the fonovving essentio1 odvontages= (1) It anoWs of obtoining pne fabffos harving on openWofk covenng, vithouf 1oss of vveft pile nlatefioL (2) It aHows of obtaining a. fancy fabrio iden tioa1 to that pfoduced by vveavfng in one oieoe vrith an inl ortant reduction in fhe number of pioks pef inch and varying oocofding os vveaving iS effeoted With one of tWo supplefnenfary tex tufeS, and a1so accordfng to the propoftion of the picks to the ground ond pne threods used in the fabric. v

3) It anoWS SifnultaneouS cuttfng of tWo of thfee pieces.

The pfooesS acoording to the inventfon is also applioable to doublepieoe velvefeen. '1'his double fabrio is constituted by tWo gfound textures between Which the ile element Works, this latter being hefein oonStituted by a supplonfentofy Weft.

The appHootfon of this neW pfocess to this fnode of weov1ng is e1feoted by odding o supp1e 1nentofy textufe to the undef textufe of to t11e top texture, of both to the undef and top fextufes. f he fanoy effect is obtained aftef' Sepafation of the gfound textures ond of the Supp1enlentofy texture, the pile loops vvhich it is desifed to fonlove ffom the gfound textufe bofng bound on the thfeads of the supp1ementary foxture, Which it Self fofn1s vvith theSe loopS ren1oved, 34 pfle fabric having ain openWork coverfng, conlplenlentory to that of the ground textufe.
